Objective:

To identify and analyze the RB1 p.E125* mutation in a bilateral retinoblastoma patient from China.

Key Findings:
  • The RB1 p.E125* mutation was identified in a bilateral retinoblastoma patient.
  • Functional analyses revealed abnormal protein localization and altered cell cycle distribution.
  • The somatic origin of the mutation was established, ruling out heritability in this patient.
Interpretation:

Limitations:
  • The study is limited to a single patient case, which may not represent broader population trends.
  • Functional analyses were conducted in vitro, which may not fully replicate in vivo conditions.
Conclusion:
